Sun Microsystems 280R manual Use the test command to test the network device, type

1.Use the test command to test the network device, type:

ok test net

2.If you connect the system to a network and the network does not respond, use the OpenBoot PROM command watch-net-allto display conditions for all network connections, type:

ok watch-net-all

For most PCI Ethernet cards, the link integrity test function can be enabled or disabled with a hardware jumper on the PCI card, which you must set manually. (See the documentation supplied with the card.) For the standard TPE main logic board port, the link test is enabled or disabled through software, as shown on the next page.

Note –Some hub designs permanently enable (or disable) the link integrity test through a hardware jumper. In this case, refer to the hub installation or user manual for details of how the test is implemented.

Following is typical output from the watch-net-allcommand:

ok watch-net-all /pci@8,700000/network@5,1

gme register test --- succeeded. Internal loopback test -- succeeded.

To enable or disable the link integrity test for the standard Ethernet interface, or for a PCI-based Ethernet interface, you must first know the device name of the desired Ethernet interface. To list the device name use either solution described below.
